Seal and Prevent Leaks in Plumbing, Machinery and More

The Neiko 419-piece O-ring assortment is a comprehensive metric sized set of nitrile butadiene rubber (NBR) rubber o-rings, perfect for personal use, or in professional workshops and garages.

O-Rings, sometimes referred to as o rings, orings or toric joints, are used in a variety of trades for sealing and leak prevention along material joints. The super durable, yet pliable NBR rubber used in this set is highly oil and UV resistance, making these o-rings ideal for use in plumbing, machinery, hydraulic and pneumatic applications. These o-rings also feature universal compatibility, presented in 32 variations sized using the metric standard. A hardshell case is included for protection and organization of o-rings by size, along with a chart detailing their inner and outer dimensions and their location in the case.



  • O-RING ASSORTMENT KIT: NEIKO introduces our Rubber O-Ring Assortment Kit. Each O-ring acts as a joint gasket to seal and protect water lines in any oil line, faucet, sink, filter, toilet, or other machinery.
  • VERSATILE & RELIABLE: Thanks to the NBR construction, these rubber O-rings are resistant to water, UV, lubricants, hydraulic fluids, gasoline, alkalis, and grease. Each O-ring creates a long-lasting seal that protects your devices from leaks.
